Add the Slipnet to the curses reporter.

This isn't terribly useful to the human observer, actually.
It seems like the most useful factors that ought to be displayed
are really the groups/bonds in the workspace and the current
"rule" (if any). Particularly, with the current design of Copycat,
it seems like the "rule" should be part of the displayed output
just the same as the modified target string.
